Production Method Of Lyocell Fiber

Lyocell fiber is made of natural wood as raw material, wood pulp is made with ammonium oxide solution as solvent, cellulose pulp is dissolved first, and made into solution, wet spinning method (or dry-wet spinning method) is applied, N-methyl oxymorine of specified concentration is used to solidize the fiber through spinning solution, and then through stretching, washing, oiling, drying and other processes. To produce Lyocell's new fiber.

The production of Lyocell fiber is different from that of ordinary viscose fiber, Lyocell uses N-methyl oxymorine to dissolve cellulose pulp directly, simplifying the production process of spinning stock. N-methyloxymorine has a recycling rate of more than 99%, making the production of Lyocell fiber more environmentally friendly. The difference of morphology and structure of Lyocell fiber determines its better mechanical properties and better dimensional stability.
